Cell phone towers killing birds, while your cell phone gives you brain cancer!

Use your blue tooth, and be aware that birds are being killed for our chatting habits:

Mobile Towers can damage bird eggs

Set a bird song as your mobile ringtone. For that may soon be the only way you get to hear from our winged friends — studies show that the increasing number of cell phone towers in cities is bringing down bird population.

While studies in Spain and Belgium have established the ill-effects of electromagnetic radiation (EMR) emitted by cellphone masts on birds, a study to be published next month by a team in Panjab University has found that EMR can damage bird eggs and embryos. The study, conducted in Chandigarh, is applicable to all Indian cities where cellphone masts are proliferating. Chennai has 4,000 cellphone towers, compared to about 200 in Chandigarh.

Researchers at the Salim Ali Centre for Ornithology and Natural History (SACON), Coimbatore, say there are enough reasons to attribute bird mortality to such radiation. "Cellphones and towers emit a very low frequency of 900 or 1,800 MHz, called microwaves. Studies have found that they can cause thin skulls of chicks and thin egg shells," says Dhanya R, a researcher at SACON.

The team at the Centre for Environment and Vocational Studies of Panjab University, headed by RK Kohli, exposed 50 eggs to EMR for durations of five minutes to 30 minutes. "All the 50 embryos were damaged. It's almost like being microwaved,

Chennai-based zoologist Ranjit Daniels says four of the 200-odd Chennai birds — house sparrow (Passer domesticus), red-whiskered bulbul (Pycnonotus jocosus), brahmini kite (Haliastur indus) and spotted dove (Streptopelia chinensis) — have virtually disappeared.

"Birds are known to be sensitive to magnetic radiation. Microwaves can interfere with their sensors and misguide them while navigating and preying," says Daniels.
